Star Wars or Doctor Who, I think.

Star Wars. Idk about Doctor Who. I’m dangerously behind on that one.

I just said Doctor Who because it has over 20 last I checked, I also said Star Wars because last I checked it had a lot.

Dc Fandom

Marvel Fandom

Power Rangers Fandom

Star Wars has the most in a single continuity. But if we are talking about a franchise with multiple continuities than either DC or Marvel.

Probably any Armored Studios fandom.
